=item msgsnd ID,MSG,FLAGS
X<msgsnd>

Calls the System V IPC function msgsnd to send the message MSG to the
message queue ID.  MSG must begin with the native long integer message
type, followed by the message itself.  This kind of packing can be achieved
with C<pack("l! a*", $type, $message)>.  Returns true if successful,
false on error.  See also L<perlipc/"SysV IPC"> and the documentation
for L<C<IPC::SysV>|IPC::SysV> and L<C<IPC::Msg>|IPC::Msg>.

Portability issues: L<perlport/msgsnd>.
